When Did Slavery End in New York State?

In 1799, New York passed a Gradual Emancipation act that freed slave children born after July 4, 1799, but indentured them until they were young adults. In 1817 a new law passed that would free slaves born before 1799 but not until 1827. By the 1830 census there were only 75 slaves in New York and the 1840 census listed no slaves in New York City.
